Two 180s for Martin Lukeman to start leg 23...

But the seventh dart into the perfect nine-darter dips below the treble 20.

And Mickey Mansell won't be shaken off! Lukeman doesn't get back to the board.

A great leg from both players.

Martin Lukeman just has to keep holding his throw here - easier said than done, of course - but that will be enough to see him over the line.

No alarms as he takes the 22nd leg to move within three of victory.

That is sensational from Mickey Mansell. If he'd missed it was almost certainly over. A bit of bottle from Mansell!

Mickey Mansell needs to find something special in this last stretch of legs if he is going to deny Martin Lukeman a first appearance in a major televised final here.

The Northern Irishman hits a 180 to get down to a finish first, but Lukeman responds in kind to leave himself on 24.

Mansell has to take out 83 - and he does! Lovely stuff.

Martin Lukeman had a real sprint to the line against Rob Cross and he'll be thinking the same here, don't get embroiled with your opponent.

He'll also be thinking about whether he can conserve energy for the final later by wrapping this up as soon as possible.

Today's champion will take home £150,000 and the runner-up £70,000, with the two losing semi-finalists pocketing £50,000 apiece.

Not bad for a week's work.

A reminder that following this match is the second semi-final between Luke Littler and Gary Anderson.

Mickey Mansell has it all to do.

Martin Lukeman hits an early 180 to take command of the 20th leg and hits double 12 to go ahead by four legs for the first time in this semi-final.

The players head off for the final break of the match - when they return, they'll play through to a finish.

First to 16 wins, remember.

This is a huge leg before the final break.

Martin Lukeman breaks the throw in 13 darts to restore his three-leg lead - much better from him on this occasion.

He's five away from victory now.

Martin Lukeman gambled. He could have split (on double seven with two darts in hand) but he gambled.

That is an absolutely massive final dart from Mickey Mansell.

One of those really, REALLY scrappy legs that sometimes mean more to win than your standard 15-darter, and Mickey Mansell gets it.

Both players have trouble on the outer ring, Martin Lukeman misses four darts for a four-leg lead, and Mansell takes it in 21 darts with a shot at double two.

Mickey Mansell has got some work to do now.

In what is a very tight semi-final, Mickey Mansell is chucking in the odd poor visit here and there, and they are proving costly.

This time it allows Martin Lukeman to open up a three-leg lead.

After Mickey Mansell narrowly misses the bull for a 111 finish, Martin Lukeman mops up to hold throw and he is back into a two-leg lead.

It is going to come down to Mickey Mansell picking his moments and going at the right time if he's going to win this.

Martin Lukeman's three-dart average (98.85) is more than five points higher than that of Mickey Mansell, he's thrown six 180s to Mansell's five and he also has a better percentage on the doubles.

Most importantly, he has a one-leg lead on the scoreboard.

That is a little bit of a scene-stealer from Martin Lukeman.

A clench of the fist from Martin Lukeman as he finishes 84 on the bull to take an 8-7 lead into the next break.

We're all square! Mickey Mansell takes out 71 to break the throw.
